The cyrus-imapd package contains the core of the Cyrus IMAP server.
It is a scaleable enterprise mail system designed for use from
small to large enterprise environments using standards-based
internet mail technologies.

A full Cyrus IMAP implementation allows a seamless mail and bulletin
board environment to be set up across multiple servers. It differs from
other IMAP server implementations in that it is run on "sealed"
servers, where users are not normally permitted to log in. The mailbox
database is stored in parts of the filesystem that are private to the
Cyrus IMAP server. All user access to mail is through software using
the IMAP, POP3, or KPOP protocols. TLS supported for security.

CalDAV and CardDAV protocols are supported since Cyrus IMAP v2.5.
